SPECIFICATION forming part of Letters Patent No. 519,635, dated May8,1894.

Application filed December 26; 1893- Serial N- 494|637- (N0 model.)

.To all whom it may concern.-

Be it known that I, LOUIS G. KREGEL, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inTrocars, of which the following is a full, clear, and exact description,reference being bad to the accompanying drawings, forming part of thisspecification.

My invention relates to certain improvements in a combined trocar andembalming needle, the object being to constructsuch'an instrument in amanner which will facilitate its use in withdrawing blood and foreign'substances from the body; and my invention consists in featureshereinafter fully described and pointed out in the claim.

Figure I is a longitudinal section of my improved instrument. Fig. II isa transverse section, taken on line IIII, Fig. I.

Referring to the drawings, 1 represents a tube having a longitudinalcavity or opening 2, through which the matter passes from the body, theinner end of the tube being reduced to a point 3, and the outer end ofthe tube having a head 4, to receive the hose of the suction pump ordevice. cavity 2, from the tapering end 3 to near the end 4, is asmallercavity or opening 5, through which air enters the body to prevent avacuum in the body, and permit the matter to flow freely through thecavity 2. The inner end of the cavity 5 ceases or stops at 6 on thetaper of the inner end of the tube, while the cavity 2 extends to thepoint 7, which is be yond the point 6, so that the suction of the pumpdoes not tend to draw matter against the mouth of the cavity 5, as itmight do if Parallel with the the inner end of the cavity 5 were evenwith or beyond the innerend of the cavity 2. The outer end of the tubehas a horn 8 extending at anangle from the tube, and the cavity 5extends through this horn, so as to be presented in a direction awayfrom the mouth of the cavity 2, and not be interfered with or stopped upby the hose connecting the suction pump or device, not shown, with thetube, and also for the purpose of permitting this end of the air cavityto be covered or closed by an elastic nipple 9, which is adapted to beslipped over the horn, and which has a plug 10 at one end. This tube 9excludes dust from the air cavity, and may also, if de sired, be used attimes for the purpose of closing the air vent when the embalming fluidis injected through the cavity 2. The horn 8 has a shoulder 11 to assistin retaining the soft, rubber nipple 9 on,.the horn, when placed there.

The device can be cheaply made and has been, by practical use, found tobe very efficient.

I claimas my invention- A combined trocar and embalming needle,consisting of a tube provided with a horn 8 and a tapered end 3 andhaving a cavity 2, and an air cavity 5, the inner end 6 of theair cavitystopping short of the inner end 7 of the cavity 2, substantially asshown and described.
